A system for performing real time quantization and analog/digital conversion of an analog waveform operating with analog input signals over one gigahertz bandwidth is realized by utilizing a CRT type device in which the electron beam is deflected by the analog input waveform. The deflected electron beam strikes a fast phosphor screen and an externally positioned target consisting of light sensitive elements arranged in a discrete pattern detects and quantizes the signal. The output of the detectors feed an encoder resulting in a binary digital output waveform. The device accepts both unipolar and bipolar video waveform and has parallel output channels such that further circuitry to be employed can operate with reduced bandwidths.

A real time data rate quantizer and analog-to-digital converter system employs an electron beam which is deflected by an analog input waveform. The deflected electron beam strikes a mosaic target in which electron beam sensitive elements detect and quantize the signal. The outputs of the detectors feed an encoder resulting in a binary digital output waveform. (Author), Supersedes PAT-APPL-649 106-76, AD-D002 333.

The power-frequency performance of microwave transistors, Gunn-Effect Impact Avalanche Transit Time (IMPATT), Trapped Plasma Avalanche Triggered Transit (TRAPATT), and Limited Spacecharge Accumulation (LSA) devices is graphically presented. Based on foreseeable advances in technology, the 1975 expected performance, with a brief discussion of underlying developments as of September 1971, is included. Important aspects of device performance in addition to power are being studied at Cornell University and the University of Michigan under contract with Rome Air Development Center. Two results from these contracts are summarized: The Effect of Temperature on the Operation of an IMPATT Diode, and Avalanche Region Width in Various Structures of IMPATT Diodes. (Author)
